Earlier this year at the Tejon Ranch near Lebec, Calif., three of the funniest guys in show business joined forces with iconic photographer Annie Leibovitz to recreate one of the most legendary trios in Disney history, the Hitchhiking Ghosts.

I can tell you, Jack Black, Will Ferrell and Jason Segel weren’t just playing parts on this one – this was a personal project for them. Each of them shared stories with me about the first time they experienced the Haunted Mansionand how it remains one of their favorite Disney Parks attractions to this day. One of them even has the attraction poster on the wall of his home, and described the chance to make this portrait as “maybe the best day ever.”

As always, Annie and her team’s attention to detail is a pleasure for any Disney fan to behold. Did you get a close look at those thumbs?

In this video, I take you right on to the set and into the makeup trailer to discover just why these grim ghosts are grinning so much.
